Which expression represents rational numbers? Select all that apply
Vladimir79 [104]

Answer:

1. \sqrt{100} \sqrt{100}

2. 13.5 + \sqrt{81}

3. \sqrt{9} + \sqrt{729}

6. \frac{3}{5} + 2.5\\\frac{3+12.5}{5}\\\frac{15.5}{5}\\= 3.1

These four options are rational;


Step-by-step explanation:

1. \sqrt{100} \sqrt{100} equals to 10 * 10 = 100 which is rational

2. 13.5 + \sqrt{81} equals 13.5 + 9 = 22.5

3. \sqrt{9} + \sqrt{729} -- 3+27 = 30

6. \frac{3}{5} + 2.5\\\frac{3+12.5}{5}\\\frac{15.5}{5}\\= 3.1

Option 4 and 5 are irrational because they include  \sqrt{353}  and \sqrt{216} which are not a perfect square and their answers will be non recurring and non terminating decimal fraction.
